FS: Ported (for 1zz) OEM intake manifold

[tmontague]

I am selling my JB weld ported intake manifold that was ported to match the 1ZZ throttle body. Not only is the opening ported but the sharp 90 degree bend into the plenum is also ported quite a bit as well.

The manifold is being sold with the oem gasket as well. I have removed the 3 threaded studs that the throttle body bolts on to so you'll need your from your stock manifold or purchase some.

This manifold was not run on a dyno but in my experience it has drastically increased the throttle response of the 1zz TB and it has improved how hard the Yaris pulls right up to red line. It has also helped down low torque but not as much as you would get from the MI intake manifold.

I am selling because I was fortunate enough to be able to purchase a used MI intake manifold. If you cannot afford the MI manifold then this is a very good compromise for a fraction of the price and it will still help with performance. The biggest difference between this manifold and the MI manifold is that the MI manifold really increases low end torque quite a bit and it has dyno pulls to prove it.







I'd recommend using RTV sealant to make a gasket between the TB and the maifold. Just make a bead around the manifold and let it sit for about 1-2 hours until it is slightly firm but still somewhat tacky. Then install the manifold. Then open the butterfly valve and make sure not RTV has been pressed inside the TB, if it has just wipe it clear with a paper towel or your finger.

Price is $150 USD OBO
